In this article we'll be using the awesome open-source nmap network scanning engine. In this example I will be preforming my scan from a Linux box. However you can use other OSs.
Nmap Network Scanning is the official guide to the Nmap Security Scanner, a free and open source utility used by millions of people for network discovery, administration, and security auditing. From explaining port scanning basics for novices to detailing low-level packet crafting methods used by advanced hackers, this book by Nmap's original author suits all levels of security and networking professionals. The reference guide documents every Nmap feature and option, while the remainder demonstrates how to apply them to quickly solve real-world tasks. Examples and diagrams show actual communication on the wire. Topics include subverting firewalls and intrusion detection systems, optimizing Nmap performance, and automating common networking tasks with the Nmap Scripting Engine.
The Insecure.org developers have announced the release of version 5.0 of Nmap, their popular network scanner and mapper. The release features nearly 600 significant changes and the developers consider it to be "the most important Nmap release since 1997". Major improvements to the network scanner include the addition of the Ndiff scan comparison tool and the Nmap Scripting Engine
What can I do with Umit?
With Umit, you have all the power provided by Nmap through its regular command line interface, and a lot more in a highly usable and portable Graphical Interface. Some of its main features include:
* Easily create powerful Nmap commands and save them as profiles to use whenever you need it
* Edit your Profiles using the Interface Editor
* Create Profiles with the assistance of a Wizard
* Group and order you scan results
* Filter hosts list by services
* Filter services list by hosts
* Compare two scan results in one of our three compare modes: text diff, graphical comparison and HTML diff
* Search scan results
* Use Umit interface through the Web
Here is a brief of new features :
* Scan scheduler
* Network Inventory
* Radial Mapper for Nmap's traceroute
* Interface Editor
* We have others packages too: Packet Manipulator
* UmitWeb
* UmitBT
* UMPA
RadialNet is a network visualization tool developed for Umit during the Google Summer of Code 2007. In Umit it's called UmitMapper. It consists in a graphical tool to illustrate the Nmap network mapping. You can see a video demonstration based on version 0.3 here.
